HUB-ATTACHING DEVICE.

Specification of Letters Patent.

Patented Nov. 6, 1906.

Application filed February 3.1906. Serial No. 299,347.

To all whom it may concern: 4

Be it known that I, MARTIN R. BRUNER, a citizen of the United States, residing at Wapakoneta, in the county of Auglaize and State ofOhio, have invented certain new and useful Improvements in Hub-Attaching Devices; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters of reference marked thereon.

The present invention has for its object to provide a simple and effectivemeans for attachin the hubs to axles or the spindles thereo and it consists in the details of construction substantially as shown in the drawings, and hereinafter described and claimed.

Figure 1 of the drawings is a longitudinal section of my invention;Fig. 2, a cross-section thereof, taken on line 2 2 of Fig. 1.

In the accompanying drawings, A designates the spindle of an axle, and B the axlecap, and C a plug of wood or other suitable material having an inclined passage (1 to supply the oil to the oil-chamber of the spind e. At the upper end of this inclined passage (1 is a springactuated valve D, consisting of a stem 1), with cone-shaped head 0, which engages with a correspondingly-formed seat e, so that when depressed the valve will open and allow oil to pass into the passage, and when pressure is removed from the valve it will automatically close the valve-openin A rivet or bolt 4. extends through the spind? A and a cup-shaped cap E to connect them together, as shown in Flg. 2 of the drawings.

A distributing-disk F is located between the outer end of the spindle A and a cap E, said distributing-disk having an annular shoulder j, which is of greater thickness than the thickness of thecap, so that the end of the cap cannot be clamped between the distributi'ng-disk and the boxing G when the nut g on the screw is tightened. The distributing-disk F is provided with aflat-sided l extension h, which is integral therewith and engages a correspondingly-formed opening in the boxing G at the outer end thereof to com el the two to turn together.

T e thimble is formed In two sections, as shown at H and I, and between said sections is held the disk K of the wheel, the-opposite disk thereof being indicated at L, and between the section H and dust-flange M said disk is held.

The boxing G fits tightly against the disks K L of the wheel, as shown in Fig. 1 of the drawings, so that the boxing and its connections will revolve together, including the oildistributing disk and tightening-nut.

When other forms of hubs or wheels are used, the outer section of the thimble' may be changed in construction as circumstances would require, and it should be understood that many changes or modifications may be resorted to in the various details of construction without in any manner departing from the essential features of the invention.

Having now fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is

A hub-attaching device consistingof a tubular spindle, an axle-cap extending over the end thereof, a boxing and a cup-shaped cap located between the s indle and boxing, a disk located between t e ends of the spindle and cup-shaped cap, said disk having a circular shoulder of greater thickness than the thickness of the cap, and a flat-sided extension to the disk engaging a correspondinglyformed opening in the boxing, and a screwshank extending from the disk and a tightening-nut thereon, substantially as and for the purpose set forth.

In testimony whereof I afiix my signature in presence of two witnesses.
